Abstract Apparatus for dispensing pasty flowable substances, and particularly for dispensing substances such as mustard and catsup for deposit on buns. The apparatus comprises a closed container having a plurality of compartments for containing mustard and catsup. A valve arrangement is associated with the container to uncover selected openings in compartments, and air under slight pressure is introduced into the container to assist in ejecting the mustard or catsup. A control is included to selectively provide for ejection of mustard, or catsup, or both.
